Container for storing foods

Abstract

A container for storing food is provided with a receptacle including a bellows, a top opening, and external threads around the opening; and a lid including a skirt including internal threads secured to the external threads, a top bossed hole communicating with the bellows, and a top frame having an n-shaped section, the frame including an inner slot; an inlet valve in the bossed hole; a trigger assembly including a spring loaded piston in the frame, and a trigger formed with the piston; a sealing ring secured to an end of the piston distal the trigger; a cylinder for receipt of the sealing ring and a portion of the piston, an inlet port fitted on the bossed hole, and an outlet valve at an end distal the sealing ring; and a cover including a peripheral opening for receipt of the trigger.

What is claimed is: 
     
       1. A food storage container comprising:
 a receptacle comprising a bellows, an opening formed at one end, and external threads formed around the opening; and 
 a lid comprising: 
 a peripheral skirt including internal threads secured to the external threads, a bossed hole formed on a top, the bossed hole communicating with the bellows, and a frame formed on the top, the frame having an n-shaped section, the frame including an inner slot; 
 an inlet valve disposed in the bossed hole; 
 a trigger assembly including a spring loaded piston disposed in the frame and through the inner slot, and a trigger formed with the spring loaded piston; 
 a sealing ring secured to an end of the spring loaded piston distal the trigger; 
 a cylinder for receipt of the sealing ring and a portion of the spring loaded piston, an inlet port fitted on the bossed hole, and an outlet valve disposed at an end distal the sealing ring; and 
 a cover including a peripheral opening for receipt of the trigger; 
 wherein both the inlet and outlet valves are closed in an inoperative position; 
 wherein a pushing of the trigger moves the spring loaded piston further into the cylinder to expel air out of the cylinder via the outlet valve; 
 wherein after releasing the trigger, the trigger is pushed outward to its inoperative position by moving the spring loaded piston to its inoperative position, thereby drawing air from the bellows into the cylinder with the outlet valve being closed; and 
 wherein in response to pushing down the cover, the bellows is compressed, thereby drawing air from the bellows into the cylinder, and expelling air out of the cylinder via the outlet valve.
